THUNDER GOLD ACQUIRES 100% OF THUNDER LAKE PROPERTY, SHEBANDOWAN GREENSTONE BELT, ONTARIO

Thunder Gold Corp. has executed a definitive agreement with Clifford Hickman (the optionor) to acquire a 100-per-cent interest in the Thunder Lake property, consisting of 29 mineral claims, totalling 625 hectares. The property is immediately west and contiguous with the company's flagship Tower Mountain property located 40 kilometres west of the port city of Thunder Bay, Ont.

The company can earn a 100-per-cent interest in the property by issuing 250,000 common shares of Thunder Gold to the optionor, subject to a four-month hold period. The optionor retains a 2-per-cent net smelter royalty on all mineral and/or gas production from the property, half of which may be purchased, at any time, by the company for $1-million. The company also retains the right to match any bona fide offer the optionor may receive on the remaining 1-per-cent NSR. The terms outlined are subject to approval by the TSX Venture Exchange.

Wes Hanson, PGeo, president and chief executive officer, stated: "Acquiring the Thunder Lake property increases the footprint of the Tower Mountain property to over 7,625 hectares, providing additional future working space that may be invaluable as we continue to advance and derisk Tower Mountain. Large-scale resource opportunities require vast working space, and the Thunder Lake property offers space in addition to prospectivity for nickel, copper and gold based on historical assessment reports."

Tower Mountain property highlights:

• January, 2026, mineral resource estimate as summarized in Table 1;
• All in discovery cost of $3.95 per inferred resource ounce;
• Year-round paved highway access;
• 40 kilometres from the port of Thunder Bay, Ont.;
• Road, rail and hydro at property boundary;
• 15,000-metre resource definition drill program in progress.

About the Tower Mountain gold property

The 100-per-cent-owned Tower Mountain gold property is located adjacent to the Trans-Canada Highway, approximately 40 kilometres west of Thunder Bay, Ont. The 7,625-hectare property surrounds the largest, exposed, intrusive complex in the eastern Shebandowan greenstone belt where most known gold occurrences have been described as occurring either within, or proximal to, intrusive rocks. Gold at Tower Mountain is localized within extremely altered rocks parallel to the western contact of the intrusive centre. Diamond drilling has established an initial indicated resource of 500,000 ounces of gold with an inferred resource of 3.0 million ounces of gold parallel to the western contact of the intrusive centre. Gold mineralization starts at surface and persists to vertical depths of 500 metres. Approximately 75 per cent of the perimeter surrounding the intrusion offers identical geology, alteration and geophysical signatures, representing a compelling exploration opportunity. A second exploration target, parallel to the Thunder Lake fault, extends from the northern limit of the current mineral resource pit shell, 5,000 metres to the southwest. Drilling in 2026 identified widespread gold mineralization at surface, within a broad, 100-metre-plus sequence of Timiskaming-type conglomerates overlying the fault. Gold grades are identical to those reported along the western contact at Tower Mountain.
